Question

How do you multiply `(x ^ { 2} + 8x + 2) ( 7x + 6)`?

Answer 1

`color(blue)(=> 7x^3 + 62x^2 + 62x + 12`

Explanation:

`(x^2 + 8x + 2) 8 97x + 6)`

`=> x^2 * 7x + 8x * 7x + 2 * 7x + x^2 * 6 + 8x * 6 + 2 * 6`

`=> 7x^3 + 56x^2 + 14x + 6x^2 + 48x + 12`

`color(blue)(=> 7x^3 + 62x^2 + 62x + 12`
